Application filed July 13, 1926. Serial No. 122,191. V

invention relates to fire curtains and more particularly to a fire curtain made up of a lurality of flexibly connected members.

It is a purpose of my invention to providetially close the same adjacent the ends thereof to thus prevent the passage of flames through the channels of the passages and through the guide members.

It is another purpose of the invention to provide end members on the flexibly connected members of the curtain for preventing abrasion of the metal of the flexibly connected members against the guides and also limiting the lateral movement of the curtain at right angles to the wall upon which the guides are mounted. V 3

Other objects and advantages of the invention will appear as the description of the accompanying drawings proceeds. However, I desire to have it'distinctly understood that I do not intend to limit myself to the exact details shown or described, but thatI intend to include as part of my invention all such obvious changes and modifications of parts as would occur to a person skilled in the art' and as would fall within the scope of the claims.

In the drawings:

Fig. 1 is a perspective view of a fire curtain embodying my invention, the guide membersthereforbeing partly broken away.

Fig. 2 is a section taken on the line 22, of Fig. 1.

Fig. 3 is an enlarged, fragmentary, perspective view of one edge of the fire curtain and the adjoining guide member.

Fig. 4is a perspective view of one of the endmembers employed on the fire curtain,

and Fig. 5 is a fragmentary section through one of the guide members and the co-operating portion of thefire curtain.

Referring in detail to the drawings:

I My .improved'fire curtain is shown as being mounted over an opening 10*in a wall 11 and as comprising a reel 12 having a shaft13 which is mounted'within a housmg 14,-the shaft being driven by means of a sultable bevel gear 15 mounted thereon, whlch is actuated in any. desired manner by means of a bevelled pinion 16 meshing therewith. Mountedupon the reel 12. is the fire curtain 17 which is made up of'the elongated, channelled members 18 which are hingedly connected together by-means of the curled-over portions 19 and 20 on adjoining members which interengage, as clearly shown in Fig; 5. Channelled guide members 21 receive the opposite edges of the curtain '17 between the flanges 22 thereof. I

Onytheouter flange 22 of each. of the guide members 21 is mounted an inwardly extending ear 23and co-operating with eac of said ears 23 is a hook member24 having a base portion 25 secured to one of themembers 18, said base portion being Curved as indicated at 26 to conform to the curvature of'the member 18 upon which the same is mounted. Each of the hooks 24 has an outwardly extending portion 27 that is substantially perpendicular to the base 25 and a substantially right angula'rly extending hook portion 28 that is adapted to engage over the ear 23 with which the same 00- operates, as shown in Fig. 1. When the hooks 24 are in engagement with the ears 23 the downward movement of the curtain 17 is stopped, the hooks being so placed that the curtain 17 has completely closed the opening 10 when the hooks 24 engage with said ears 23. The books 24 are furthermore placed nearer the edges of the curtain 17 than are the end flanges 29 of the reel. Thus the hooks can lie in the position shown in Fig.2 when the curtain 17 is rolled up on the reel 12 without coming into engagement ion edge 32 of the rib 31 being substantially flush withthe longitudinally extending rib portions 33' on each of the sections 18' to thus close the passage between the guide flanges 22 and the Curtain 17 which would otherwise exist because of the concave form a means of therivets 36.

rovided that overlie the ed 'es of alternat- P e ing sections 18, said end members 341 having flanges 35 that fit against the convex sides,

of the members 18, being secured thereto by The members 34- are provided .With rounded knobs or enlargements 3? that overlie the joints formed by the curled-over portions 19 and 20 between the members 18 at the edges thereof to thus protect said joints. The members 34pmventabrasion or". the edges of the curtain 1"! and also of the convex and concave faces of thefn'iembers 18 and the ribs 31 due to en? gagement with the guide member 21 and als'o,by filling a large portion otthe space between the flanges 22, preventmovement ot the edges of the curtain at right angles to thewall 11.

What I claim and desire to secure by Letters Patent is:

1. In a'fire curtain, a reel, a closure member comprising a plurality of flexibly connected sections mounted on said reel, a guide member engaging an edge of said closure member, a stop on said guide member and a hook on the closure member engaging said stop to limit the downward movement of said closure member. v

2. In a fire curtain, a reel, a flexible'closure inember mounted thereon, a guide member engaging an edge of said closure member and co-operating stops on said closure member and guide member to limit downward, movement of said closure member, comprising a'hool: on one of said members andan ear engaged by said hook on the other of said members.

3. in a tire curtain, a reel, a flexible closure member mounted thereon, guide members engaging the opposite edges of said closure member and co-operating stopson,

said closure member and said guide members to limit the downward movement of said closure member, each comprising ahook on one of said'members and an ear engaged by said hook on the other of SH1d. 111811'lb6lS. In testimony whereof I afiix my signature.
